Modern weapons have a terrible effect and are almost unbearable by the nervous system. Who can say that he has not been frightened in battle? Discipline in battle becomes the more necessary as the ranks become more open, and the material cohesion of the ranks not giving confidence, it must spring from a knowledge of comrades, and a trust in officers, who must always be present and seen. What man to-day advances with the confidence that rigid discipline and pride in himself gave the Roman soldier, even though the contest is no longer with man but with fate? To-day the artillery is effective at great distances. There is much liberty of movement for the different arms. The apparent liaison between arms is lessened. This has its influence on morale. There is another advantage in reliable troops, in that they can be extended more widely, and will consequently suffer smaller losses and be in better morale for close conflict. The further off one is, the more difficult it is to judge of the terrain. Consequently the greater is the necessity for scouting, for reconnoitering the terrain by skirmishers. This is something that the Duke of Gramont forgot at Nordlingen, and which is often forgotten; but it constitutes another important reason for the use of skirmishers. The formation in rank is a disciplinary measure against the weakness of man in the face of danger. This weakness is greater to-day in that the moral action of weapons is more powerful, and that the material rank has the inherent lack of cohesion of open order. However, open order is necessary to economize losses and permit the use of weapons. Thus to-day there is greater necessity than ever for the rank, that is for discipline, not for the geometrical rank. It is at the same time more necessary and doubly difficult to attain. In ancient battle unity existed, at least with the Greeks and the Romans. The soldier was known to his officer and comrades; they saw that he fought. In modern armies where losses are as great for the victor as for the vanquished, the soldier must more often be replaced. In ancient battle the victor had no losses. To-day the soldier is often unknown to his comrades. He is lost in the smoke, the dispersion, the confusion of battle. He seems to fight alone. Unity is no longer insured by mutual surveillance. A man falls, and disappears. Who knows whether it was a bullet or the fear of advancing further that struck him! The ancient combatant was never struck by an invisible weapon and could not fall in this way. The more difficult surveillance, the more necessary becomes the individuality of companies, sections, squads. Not the least of their boasts should be their ability to stand a roll call at all times. The ancients often avoided hand to hand conflict, so terrible were its consequences. In modern combat, there never is hand to hand conflict if one stands fast.
